WPF入门教程系列十一——依赖属性（一）WPF入门教程系列十五——WPF中的数据绑定(一) 添加ClickAction的实现

 <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">通过上面两步，我们将准备工具全部做完了，现在需要在.xmal文件中给Button按钮的Command属性绑定了一个方法叫做ClickSaveAction，DataGrid控件的SelectItem绑定MainWindowVM（ViewModel）中的AreaVM属性。
1. <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">在Visual <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">Studio <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">2022中打开MainWindows.xmal文件。

2. <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">对DataGrid的SelectItem进行了数据绑定。具体代码如下：

<DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">

复制代码

3.将ClickSaveCommand绑定到Button按钮的Command属性上，这个ClickSaveCommand指令将代替<Button x:Name="btnSave" Height="22" Width="120" Command="{Binding ClickSaveAction}" >保存</Button>按钮的click事件，将数据<Button x:Name="btnSave" Height="22" Width="120" Command="{Binding ClickSaveAction}" >保存</Button>到数据库。具体代码如下：

<Button x:Name="btnSave" Height="22" Width="120" Command="{Binding ClickSaveAction}" >保存</Button>

复制代码

注意：Command属性仅仅作为Click行为的绑定，其他行为，如鼠标移入、移出等事件，要使用另外的MVVM方式进行绑定。
4.MainWindow.xmal的全部代码如下：

数据已经<Button x:Name="btnSave" Height="22" Width="120" Command="{Binding ClickSaveAction}" >保存</Button>到数据库，如下图。

7.如果我们要让<Button x:Name="btnSave" Height="22" Width="120" Command="{Binding ClickSaveAction}" >保存</Button>按钮禁用，可以将执行的方法返回为False，具体代码如下：

七、ComboBox下拉事件转为Command命令
用于 <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">DataGridComboBoxColumn <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">显示有一组项可供选择的数据，例如枚举。 <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">DataGridComboBoxColumn <DataGrid x:Name="gridArea" Grid.Row="1" d:ItemsSource="{d:SampleData ItemCount=5}" AutoGenerateColumns="False" HorizontalAlignment="Left" VerticalAlignment="Top" SelectedItem="{Binding Path=AreaVM, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}">允许用户从下拉列表中选择项。本文通过将Command命令绑定到comboBox的SelectionChanged事件上，实现自动刷新用户选择的省份的相应城市信息。
在WPF中默认的Command绑定往往不能满足覆盖所有的事件，例如ComboBox的SelectionChanged事件，DataGrid的SelectionChanged事件等等，这时就可以用到一个扩展库，来实现事件绑定Command。
